ADP Implementation Consultant interview questions

I had a reference when I applied so I received an interview quickly, however, when I was called by ADP the person interviewing me made it seem like he wasn’t an employee and that they had outsourced this interview. He started asking me questions that were already covered on the application and did not seem to be aware that I had a reference. It did not feel professional and he didn’t really even interview me. A few weeks passed and I never heard anything. I was already skeptical because this position was on their website earlier, taken down, and then put back up again when I applied so I’m not entirely sure if it’s a role that they are truly motivated to fill. I would not recommend applying here.
